Thread: Integration Problem

Hello, I'm new here and I have a problem that I can't solve. I thank you in advance for ANY help you can give me. I know things are written to scale, but I couldn't find where to access the symbols. Thank you so much!



∫ x - 1
----------dx
2
x - 4x + 5

this bottom x is squared and the -- lines are the divided by lines. Then the formula is multiplied by dx. Thanks!

note that

for the first integral, do a substitution of , for the second, complete the square in the denominator, and try to get the arctangent integral.

can you continue?

that's not true. if you expand the denominator of what you wrote, you get

oh, okay! I think so. Thank you!

Ah whoops my bad. Don't know what I was thinking =S
